TO ALL WIIOM IT MAY CONCERN:

Be it known that I, DAVID IV. BAKKER, of Newl Haven, in the county of New Haven, arid State of Connectcut, have .invented a new Improvement in Ash-Sifter; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view,

Figure 2 a top view with the cover removed, and in Figure 3 a section on lline w m of tig. 2.

This invention is designed for sifting the ashes which-come from coal lires, or like purposes, and consists inthe peculiar construction of the sieve, and in the arrangement for agitating the ashes in order to cause them to pass through the sieve.

To enable others to construct and use my improvement, I will proceed te describe the suine as illustrated in the accompanying dra-wings.

A is a case, formed from metal or other suitable material, having a flange, a, turned outward upon its lower edge, which forms a support for the sifter to rest upon, B is the wire netting or sieve, which is cut to the proper size, and stretched overa cylinder, C, as seen in iig. 3, and forced up into the case A, and in that position secured by rivets d, or otherwise, the cylinder C extending below the flange a, so as to enter the barrel or box upon which the sifter rests. Centrally through the sieveB is pivoted the beater D, which may be any desirable number, hereY shown as four. From the said beaters a handle, E, entends up and through the case, as seen in fig. 3, a slot,f, (as seen in fig. 1,) being formed sothat the handle and beaters may be moved to the right and left, as denoted in blue and red, fig. 2. The slot'fis protected by acover, F, extending in and downward, so as to prevent the ashes from escaping through the said slot. The bearing for the pivot h is formed by a sleeve, 1', inserted through the sieve, and a plate, m, above, and n below, and a nut, s, upon the lower end of the pivot, which secures the parts together, and forms a strong and secure bearing for the beaters. The ease is closed h v a cover, H, as seen in g. 1.

The use of the sifter is as follows: Set it on to an open barrel or other suitable receptacle, so that the cylinder C will enter and the llange a rest upon the said receptacle to support the sifter; then remove the cover,

-pour the ashes on to the sieve or netting B, replace the cover, then move the handle E from right to left, :is

denoted iu blue, fig. 2,- stirring the ashes and cinders until they have become separated, and the ashes passed down through into the receptacle; then-remove the cover; the clinkers seen may be picked out; then by other movements of the beaters the enders so disturbed as to bring other elinkers to the top, and so on until all are removed,` and this inthe most convenient and simple manner.

Having thus fnllyldescribed my invention, what I claim as new and useful, and desire to secure by Letters Patent, is- I 1. In combination with the case A, and sieve or netting B, I claim the beaters D, operating substantially in the manner herein set forth.v

2. In combination with the beaters D, the -handle'E, and` ease A, I claim the protecting flange a.

3. The combination of the plates m and it and sleeve with the beaters D and nettingr B, when construct-ed so ns t0 form the hearing for the beaters, substantially in the manner herein set forth.
